ELECTRICALLY-OPER ATED AGRICULTURAL IMPLEMENT.

*Y `'it'petica'cion of Letters Patent.

1 v f Application filed December 30, 1369. Serial No. 535.569.

Be it lmown that I, Cims'rmn TAURMAN, a citizen ot the United*Cineinnatn in the county of Hamilton and State ot' (lino. have inventedcertain new and ns vvluiproieiiients in .lileririeallv- OperatedAgricultural Implements, oi wliieli the l? l wing a Speeitieatiuii.

This invention relate.Q toeleetrieally opi-12 I ated .'igrieulturalimplementsA and one ot the v -an elet-tric system for propelling anagi'ieul` i guide the implemente: at the oppositeends thereof,

' 4and quickly. 1 L- y n f' Another ohjeet of 'the invention is ioprotural implement to and fro over a large tract of lanzlto cultivatereliesameeeorion'iieally vide an electric System comprising a serie 'ofpoles loca ted at opposite ends ot' a field to be cultivated, said polesSupportingjr f ruide line aires supported at their ends upon thekwires.: and providing positive and negative i :ind a iirueli'earryingtrolleys in i contar with the liniatirel.. Ieaid trueli liaving;mounted thereon agricultural implements of the reipiired type atoppoiieenih tliereut` so that the truek nia) be iiioi'ed iu oppositedirections by raieing and lim'ei'iug motorek :incl a controller.`

Still another olipet of the invention is to said trut-l: carrying also apair ot'elei'trie provide an electrically operated agrieuliural l limplement comprising av trunk having a tower'supported thereon and apair of trolj leys connected to the tower to engage the; line wires ot"the si'gtein, said trolley wires l being'br Supported at intervals byportable towers mounted on wheels and adapted to'be l lifted from theground by the trolley :is the agricultural implement passes the saine,said portable towers being deposited `upon the ground in properpositionr to support the line wires extending aeros's the field. Anotherobject ofthe invention is to prol ride a simple and ellieient eleetrie svsteni,

hy n'iean` of whieh an agricultural implement may be conveyed bark andfoi-th across States, residing at i I poles. Fig. i

Referringto the drawings the numerals l 7 design-.ite pole?l located inSeries at the ends vS0 of tlie'field to be rultivated.

iuii'lerst'a-d that. these poles are. located at to the innereizlesofthe poles l near their upper ends are the braeketS 2- ariiil 5.saidv brackets eaeli having a curved arm 4, Supported upon each of themarred aries 4 and 5 are guide wires 6, 7 Wlii'eli are supplied with anelectric current from a suitable souree at one or both ends of thefielih 'lhe positive and negative trolleymires S and 9 are eaeliprovided 'with a bracket 10 upon which is journaledtlie grooved wheels11 mounted to run upon the `guide wires 6 and 7, as shown moreparticularly in Fig. 1. The trolley wires S and 9 are separated 'bymeans of :i suitable space bai" 12. The portable towe for supportingthe. trolley lines at points between the poles l eac-h coniprise the(livel-ging bars 13, the standard 14, the

. cross har l5 and .the arms 16, the latter bemer provided each withY aterminal weight or ball 17. A ground wheel 1S is joui-nailed ab At theupper end of the Standard .14 is a suitable It is to be,

yoke/19 having inwardly curved varms 20, 21 and supportedV uponthesearms are they trolley wires'8 and 9. The agricultural implementcomprises, a` truck providedl with a platform 20" yhaving journaleditliereom a.

pair of ground wheels 21.y A. pilot wheel 22is journaled in a suitableyoke 23 underneath the platform 20', said i ilot wheel be# ing operatedby means of a i andk wheel 24' for steering the truck. Y

A pair of electric motors 25 is supported I under the platform 20, theshafts 26 ofsaid' motors being providedwith beveled ears 27 which engagea beveled wheeli28 on t e shaft of the ground wheels "2R-*as shown moreparticularly in Fig. 7. 'Wires a: lead from the motors to a suitablecontroller 29 mounted upon the steering post and providedwith site asiitable lever 30 forreversiiig the moven ment of the truck. e Seats 3lfor the driver trolley wire 8 and as the trolley posts the portabletowers the latter are lifte are mounted upon the platform 20 in oppo Yeither direction.

Shafts 32 are j'ournaled onei'at each end ofL the platform 20* andsupported upon these shafts by means of brackets 33 arethe one of theshafts 32, and provide VVshafts 34, each provided with a seriesof diskplows 35.

For vraising and loweringthe disks 35 a suitable lever 36. is" con ectedto with a connecting-rod'` 37 whichv extends to a suit- 'at which theimplement is to bemoved. A.

able lever 38, pivoted at'39, upona rack 40,

said lever bein operated to raise and lower the disks 35, spending uponthe direction similarlseries of diskk lows 35l are mounted u on theshaft 32 at t e opposite end of the atorm 20, said disks eing raised andowered by means of a lever 36l havin a connecting rod 37 extending to -asuita le lever 38 pivoted to a rack 40, v

Supported upon the truck 20* is a. rigid tower comprising the side framebars 41, supported upon a late 42 bolted to the y latform 20; A sha t 43extends across rom one of the fraaie-bars 41 tothe other 'and supportedupon the shaft 43am therigid trolley poles 44, 45. said poles beingvheld inr position by means of curved arms 45 formed Y upon the framebars 41. The trolley poles are secured to the arms 45 by mea-ns ofsuitable bolts 46. The trolley pole 44 at its outer enil is providedwith a grooved -wheel 47 which engages the trolley wire 9;. The trolleypole 45 is made in two telescopic sections, the outer section 45 ofwhich extends intof theA section 45, as shown inf Fi 5, isA rovided witha spring 48, one en of wliic is `connected to a flange 49 on the section45,

while the opposite end of said spring is clonnected to a similar vflange.50 on the section ositions to permit the driver to face the .ront ofthemachinewhen going inl `a Alaterally movable trolley line,

45. The spring 48 is coveredrby a sleeve 51,.

The tension of the spring'f-iO is eitertedto draw the/grooved' wheel52m' on the end of the trolley `section 45* into-"contact with the assolf the ground. After the truck passes the towers they 'are againdeposited on the ',ground.v e i n The yoperation of my invention `may bebriefly described as follows: The truck carg ryiug'agriculturalimplements of any suitable character. is moved across the field, thevvtrolley wheels passing underneath the trolley wires at the to of thesupporting` towers and lifting sai towers from the ground to place: them`on the unworked land and to.r

support the trolley wresin line with the ytrolley wheels of the movingtruck. When the truck arrives at one end of the field the controller'isoperated to reverse the motors and carry the truck across the field onis. k 'Y furrow line.' f Y From the foregoingit will be` obvious'` thatany form o agricultural implement can be connected to tric truck andthat the entire cultivation of large tracts of land can ,belreadilyaccomplished by means of my system with only slight changes in thecharaciers of the implements used. Vv'hen the mounted to move on saidguide wires, portable towers or'suppoi'ting the trolley Wires, saidportable towers cach being provided with a' yoke for supporting thetrolle wires, a truck carrying agricu tural im ements,
